Abstract
The high efficiency power management IC(PMIC) for Moblie application is proposed in this paper. PMIC is controlled with PWM control method in order to have high power efficiency at high current level. The saw-tooth generator is made to have 1.2 MHz oscillation frequency and full range of output swing from ground to supply voltage(VDD:3.3V). The comparator is designed with two stage OP amplifier. And the error amplifier has 70dB DC gain and
